How does one dispose of a bowling balls that can no longer be used?  Just in your normal garbage? If so, i don't feel comfortable doing that.  Lol.  I have like 6 balls cracked all the way around the ball. 

If you're serious, with the way equipment is made, wouldn't putting one in the fire cause a safety/health hazzard?

probably but i just kinda toss them in with the rest of the burnables and then just keep an eye on it, it doesnt really burn as much as melt so theres not really a whole of smoke..

If there not damaged, I try to sell them. Bowling alley house ball rack is a great place. Dumpster at work is the last resort.

I have a huge Doberman. When she stays outside in nice weather, I put old/cracked stuff in the pen. She plays with them all day long.
